' This invention relates in general to a folding display made of sheetcardboard andthe like, and

is more particularly described as a radiating or Sunburst type of -dis'play in which a. portion is formed with radiating ribs or utes.

An important object of the invention is in the provision of a display with radiating utes formed of a single sheet of cardboard.

A further object of the invention is in the provisionof improved means for holding-theuting in radiating position, l A still further ob'ject of the invention is in the provision of a display formed of cardboard and the like which is cut and scored to form a radiating fluting and .also foldable flatly for shipment and storage.

A still further object of the 'invention is in the provision of a display with radiating fluting having a'supporting stand and openings at the inner ends of the uting adapted to receive illumination from a central lamp which is carried by thesupport for the display. Other and- `furth'erobjects of the invention will appear hereinafter, preferred embodiments 'of ing drawings inwhich Fig. 1 isa front elevation; Fig. 2 is a side elevation; and

Various types of folding displays are singlesheets of cardboard and similar sheet material, adapted to fold flatly for storage and shipping, either together with or separately from a supporting easel or stand, and the display being readily extended or set up for display purposes.

The present invention embodies a radiating type the invention being illustrated in the accompanymade from of display, or a display with a radiating marginal edge in which the edge is formed with radiating ribs or flutes adapted to be offset or drawn inwardly from a central solid portion and thus providing radiating angular ribs which are col- 5 ored in a distinctive manner to represent -a socalled Sunburst or radiating type of display .which may also be illuminated from the interior and rear of the centralportion, thereby adding attractivenesa.distinction and difference to the display In this type of display itis necessary to draw the ribs or flutes inwardly' and to hold them in their display or set up position, from which they may be released if desired to fold the displayl5 atly either together with or separately from a rear supporting easel.

Referring now more particularly to the drawings, a blank of sheet material is cut and scored to provide a central portion I5 connected to a marginal edge I6 by a plurality of adjacent'ring portions I1. In the marginal rim portion the opposite faces o f the'material are provided with scores I8 and I9 adapted to form angular ribs or flutes 20 with inner angular ends 2| spaced from adjacent cut edges 22 at the ends of ring portions I1, the angular extremities of the ribs being adapted to extend inwardly and beingsea'ted in the angular support provided by the adjacent edges 22 when the angular utesl are drawn inwardly. The lines I8 and I9 forming the fluted ribs preferably radiate from a common center so that the ribs when drawn inwardly also radiate therefrom. In order to draw the ribs inwardly the inner angular ends 0i' one or both sides of each of the angular ribs is formed with a perforation 23 through which a fastening and tightening cord 24 may be inserted and the extremities secured together by means of a slip or permanent knot 25 so that by 'inserting the cord through the perforations and drawing it up tightly the ribs will all be seated in the angular grooves between the rim portion Il. If only oneof the sides of each rib is provided with a perforation 23'the other side of the ribmay be formed with a notch or recess 26 in the edge which prevents or eases the contact with the cord or string 24, thereby reducing the friction and the force necessary to pull in the radiating ribs by means of the fastening cord.

In order to support a. display of this kind a foldable easel has a portion 21 xed by adhesive t0 p the back of the central portion I5 of the f' display with asupporting wing 28 hinged thereto and foldable rearwardly at right angles where 55 it is nem in nxed position by a locking tab ze also hinged to the back portion 21 and engaging in a recess 30 in the'hinged portion 28 for hold- `of the central lportion comprising a front 32,

bottom v33 and two lattachment portions 34 adhesively secured to the central portion and having scores 35 ,at the angular corners of the structure adapting it to fold flatly as shown in Fig. against the front of the display in folded condition. The extremities 36 of the front lmay be' rounded and provided with reduced tabs 31 whichv are inserted through appropriate openings at the front of the central portion I5 for holding the shelf in upright or extended display position, the extremities of the top or shelf 35 being cut free from the rounded portions 36 so that the ends of the shelf may extend beyond the curved portions of the support as shown more clearly in Fig. 1.

In the form of the invention as shown in Figs. 8 to 13 inclusive, a blank of sheet material has a central portion 40 with radiating scores 4| and 42 on opposite sides to provide angular iluted ribs 43 and with scores 44 and 45 on opposite sides to provide the supporting and connecting ring portions 46. The .ends of the ring portions are separated from angular ends of ribs 43 and providing a. central notch 41 and outer angular supporting portions 46 for seating the ribs therein wit a recess 49 in each edge to provideal light aper ure at each outer side of each of the ribs for illuminating the outer surfaces of the ribs if desired. n v

Although both forms of the invention are shown as having substantially circular outer edges it is apparent that the outerV edge may be square, rectangular, or of any other desired shape or outline.

In the form shown in Figjs the mwer edge 50 str ight supporting edge when the uting or ribs is drawn inwardly at the back of the central portion to provide a more stable support for the display in connection with an easel or other suitable standard connectd to the back thereof. The inner ends of the ribs may be provided with perforations as in the other form by which they are drawn inwardly and seated in the notches 41 and angular projections 46,'-or some of the inner rib projections may be formed with hooks-5| at one side thereof adapted to extend outwardly from the ribs and to engage in spaced slots 52, of a back plate 53, which hold' the ribs inwardly and in their radiating position. These slots, 52 are so positioned that the hooks 5| cannot be 'inserted therethrough until the angular-rib structure is pressed inwardly at the margin .of the central portion 40 and the hook of the projection engages the slot to prevent its disengagement except by manual attention-thereto. One portion ofthe back plate 53 is preferably comprised of a single-sheet of material with the upper and lower central portions 56 and 51, attached to the back plate by adhesive and wings 59 which fold against the back plate or are extended at rightangles `theretoin supporting position. Hinged to the upper central poi-tion 56 is a brace 60 adapted to be' bent parallel to the back plate 53 and having a perforation 6| therein through which an electric lamp socket l62 may be inserted and held so that a lamp'63 may be disposed within an opening 6'4 of the back plate sc that its lighting ele- \aof the blank is cut to provide a substantially.

ment 65 is substantially in line with the openings 43 at the sides of the ribs 43 and back 'of the central plate 40.

To hold the supporting easel -wings in position they are provided with slots 66 and 61 and the brace 66 is provided with corresponding projectionsand hooks 68 and 66 on opposite sides so that the projections and hooks are inserted through the slots and engagedly held thereby against accidental disengagement or collapsing movement, the projections and hooks being cut out of an irregular recess of which the supporting easel is made so that it too-may beI cut, scored and formed of one piece of material. If the lower part of the easel extends over one of the rib locking projections5l, a. corresponding slot 52a must be cut in the easel as shown more clearly in Fig. 102

When this display is to be illuminated, an ele'ctric lamp 63 is inserted in the brace before the easel is set up and electric light wires 1| extend from the outer side of the brace where they do not interfere lwith the display. By painting or coloring the sides of the radiating ribs the light' This form of the invention may also be collapsed flatly by disengaging the easel parts, removing the lamp therefrom, and disengaging the rib holding projections 5| from the slots 52 and 52a which allows the main display sheet to be spread out at although attached at one portion to the back plate 53. It is -obvious that a great variety of diiferent displays can be made embodying the radiating rib or fluted designs which may be made in accordance with this invention from a single sheet of cardboard orsimlar material cut, scored and formed as herein set forth and described.
